Decisions

  1. Secondary groups: We will have a minimal number of standard secondary groups in the DICE world and there will be a managed way of creating additional secondary groups.
  2. Calendar system: We recommend staff to use the central calendar system that should be available by the end of May. The Division will not be providing its own calendar service.
  3. User web pages: We will recommend that user web pages will have URL homepages.inf.ed.ac.uk/user. Other alternativer URLs mentioned in Neil's reports will be implemented as redirects.
  4. /volatile, /public and /yesterday The following filesystem areas will be created: [See relevant section for full details.]

Actions

NB: this section is now not a summary of all actions. Instead it includes:
  1. Actions Arising: CEG to discuss machine purchase mechanism. (noted 2002-02-19) Carried forward
    [Alastair/Jeremy/Ken]
  2. Actions Arising: List of modules to be published. (noted 2002-02-19). Gordon has started to create this list but further work is required. Carried forward
    [Gordon]
  3. Reports/LCFG technology: All maintainers of LCFG components should do a minimum conversion. Ongoing.
    [All component maintainers]
  4. Provide revised report layout and any special HTML format requirements. Carried forward.
    [Jeremy]
  5. Use of XDM and issues of speeding up deployment of DICE. Carried forward.
    [CEG]
  6. The auto-generated test page has received feedback and comments will be incorporated. Ongoing.
    [Alison]
  7. Deployment tasks need to notify Alison what types of documents they will be producing. Ongoing.
    [All deployment tasks 'owners']
  8. Reports/Kerberos: New accounts are needed and a full set using EUCS unique usernames is being worked on. Mail Simon if you want to enable access to your account while Tim is away. Although most of the milestones listed in the new progress pages are done this is for a test system; more needs to be done to make this a production system. Ongoing.
    [Tim]
  9. Reports/Networks: Work is being done on components and filters. The report is about to get a major re-write. Ongoing.
    [George]
  10. Reports/Config Editor: There is a possible bottleneck over rfe because of the load on Simon. Paul to discuss it with Simon. This has been partially resolved. Ongoing.
    [Paul/Simon]
  11. DICE deployment publicity: Site managers should make sure that this publicity is provided.
    [Alastair/Jeremy/Ken]
  12. Conversion of accounts to UUN: Site managers should contact those users who will need to change their username to warn them again of the need for the change and should arrange for a list of things to change/look out for.
    [Alastair/Jeremy/Ken]
  13. Arrange various cross-group technical meetings.
    [Alastair]

Minutes

  1. Corrections to Minutes: Neil noted that under action 5 (Reports/AMT) it should have reported that Neil had supplied Tim with the LDAP data to be held.

  2. Actions arising from minutes of last meeting (2002-03-5)
    1. Actions Arising: CEG to discuss machine purchase mechanism. (noted 2002-02-19) [Alastair/Jeremy/Ken]
      Carried forward
    2. Actions Arising: List of modules to be published. (noted 2002-02-19). Gordon has started to create this list but further work is required.[Gordon]
      Carried forward
    3. Actions Arising: Resources for om: Paul will specify the command-line interface and Simon will implement it.
      Done
    4. Primary/Secondary groups: decide which secondary groups are needed. (noted 2002-02-19) Neil produced a secondary groups report. Nobody had made any comments. He had suggested seven standard secondary groups. It was decided that we will have a minimal number of standard secondary groups in the DICE world and there will be a managed way of creating additional secondary groups.
      Done
    5. Reports/LCFG technology: All maintainers of LCFG components should do a minimum conversion. [All component maintainers].
      Ongoing
    6. Further investigation needed to extract report changes and list of changed reports [Jeremy/Neil].
      Done
    7. Provide revised report layout and any special HTML format requirements. [Jeremy].
      Carried forward
    8. Finish Goals/Milestones page [Jeremy].
      Done
    9. Use of XDM and issues of speeding up deployment of DICE. [CEG].
      Carried forward
    10. Use of calendars to be investigated, especially central pilot scheme [Jeremy]. Jeremy had sent round a report on this to cos@inf. He recommends that staff should use the central service that is to be available by the end of May and that the Division will not be providing one.
      Done
    11. Progress/Authorisation: account disabling flags to be clarified. [Neil]. Neil and Simon confirmed that an account disabled flag would be stored in the LDAP user account information and this would affect the roles that a person was assigned to. As a knock-on effect the (changed) role information would affect their authorisation status.
      Done
    12. The auto-generated test page has received feedback and comments will be incorporated. [Alison].
      Ongoing
    13. Deployment tasks need to notify Alison what types of documents they will be producing. [All deployment tasks 'owners'].
      Ongoing
    14. The EUCS cmsweb s/w is to be evaluated. It would be interesting to know what other software was evaluated before EUCS chose to write their own in case it would be relevant to us.[Chris]
      Done
    15. AMD needs some debugging. George is getting a test machine. [George].
      Ongoing
    16. Reports/Kerberos: New accounts are needed and a full set using EUCS unique usernames is being worked on. Mail Simon if you want to enable access to your account while Tim is away. Although most of the milestones listed in the new progress pages are done this is for a test system; more needs to be done to make this a production system. [Tim].
      Ongoing
    17. Clarify situation over users' whose login names will be changing under DICE [Alastair]. Discussed under item 6.

    18. Reports/Network: Work is being done on components and filters. The report is about to get a major re-write [George].
      Ongoing
    19. Finalise source for generating hosts lists for SSH public keys. [George]. George had suggested that there was a need for a way of mapping kerberos host identifiers to network identifiers and that it should come from the LCFG map by post processing.
      Done
    20. Reports/Config Editor: There is a possible bottleneck over rfe because of the load on Simon. Paul to discuss it with Simon. This has been partially resolved. [Paul/Simon].
      Ongoing
    21. Neil needs comments on the URLs proposed for home webspace serving. He'll post to COs. [Neil]. We will recommend that user web pages will have URL homepages.inf.ed.ac.uk/username. Other alternativer URLs mentioned in Neil's reports will be implemented as redirects.
      Done
  3. /yesterday, /risky, /public - principle and implementation:

    All three file system areas were accepted on principle but there would be no /risky/username mount points. The /yesterday mount information would be a property of a partition (not a username).

    The /risky filesystem would be renamed /volatile.

    /public was accepted as the appropriate file system name. There would be /public/username/{web,cgi}. The latter two would be held on single logical file systems (possibly the same) on the homepages webserver.

    /yesterday/home was accepted as the appropriate file system name. The /yesterday/home/username map would be constructed from the partition attribute of username in LDAP together with the yesterday (or some such) attribute of the named partition.

  4. nsu:

    nsu would exist under DICE and would change the effective uid of the person using the command on the local machine. It would be effective for remote access to files only as long as we are using NFS, but would be ineffective once a new file system was adopted. Secondary groups should be used in preference to nsu (and something like cvs in preference to both).

  5. DICE deployment publicity:

    Bill reminded the meeting that we need more publicity about how DICE deployment is going to effect people. Alastair mentioned that the effects were very site specific. Site managers should make sure that this publicity is provided.

    [ACTION: Alastair/Jeremy/Ken]
  6. Conversion of accounts to UUN:

    The conversion of usernames to the UUN versions may be quite time consuming especially for any conversions within files owned by the user concerned. Some people may wish to change fairly soon since they may be less busy now than later. Site managers should contact those users who will need to change their username to warn them again of the need for the change and should arrange for a list of things to change/look out for.

    [ACTION: Alastair/Jeremy/Ken]
  7. Review of Goals/Milestones

    Not discussed for lack of time.
